To find: If row 2 of a 3 by 3 determinant is multiplied by k and the result is added t the entires in row 1 , there is no change in the value of the determinant.
Answer to Problem 65AYU
Hence we see that there is no change in the value of the determinant
Explanation of Solution
Given information:
Calculation:
let there be a 3 by 3 determinant (A)
When row 2 is multiplied by k.
The value of determinant can be given as
When the result is added to the determinant (A)
The value of determinant B is
Hence we see that there is no change in the value of the determinant.
